[Bug 625383] Re: grub hangs at early booting after handoff from PXE
We fixed this in the cert lab by using chain.c32 rather than LOCALBOOT. As far as I know, this problem was due to a PXE BIOS bug rather than a syslinux change, although it's possible that an otherwise innocuous syslinux change managed to tickle some previously undisturbed PXE BIOS bugs. ** Changed in: syslinux (Ubuntu) Status: Triaged = Won't Fix ** Changed in: syslinux (Ubuntu) Assignee: Canonical Foundations Team (canonical-foundations) = Colin Watson (cjwatson) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/625383 Title: grub hangs at early booting after handoff from PXE -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 625383] Re: grub hangs at early booting after handoff from PXE
Release-noted, insofar as it's possible: * Some users booting machines from the network using PXE, and using the `LOCALBOOT` facility in Syslinux to hand off to a local hard disk, found that there was no argument that would successfully cause a local boot. Syslinux provides a `chain.c32` COM32 image which is less reliant on PXE BIOS implementation details.

Yes, it doesn't even get to accepting Shift, so it's as mentioned by Colin: this affects syslinux, not grub. -- grub hangs at early booting after handoff from PXE https://bugs.launchpad.net/bugs/625383 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 625383] Re: grub hangs at early booting after handoff from PXE
It seems unlikely to me that this is a GRUB bug. The evidence suggests that GRUB is simply not being loaded at all. Here is the Syslinux documentation on LOCALBOOT, and note that the permissible values for PXELINUX are *not* the same as for ISOLINUX: LOCALBOOT type [ISOLINUX, PXELINUX] On PXELINUX, specifying LOCALBOOT 0 instead of a KERNEL option means invoking this particular label will cause a local disk boot instead of booting a kernel. The argument 0 means perform a normal boot. The argument 4 will perform a local boot with the Universal Network Driver Interface (UNDI) driver still resident in memory. Finally, the argument 5 will perform a local boot with the entire PXE stack, including the UNDI driver, still resident in memory. All other values are undefined. If you don't know what the UNDI or PXE stacks are, don't worry -- you don't want them, just specify 0. On ISOLINUX, the type specifies the local drive number to boot from; 0x00 is the primary floppy drive and 0x80 is the primary hard drive. The special value -1 causes ISOLINUX to report failure to the BIOS, which, on recent BIOSes, should mean that the next boot device in the boot sequence should be activated. In addition, the Syslinux 4.00 changelog says that -1 is also supported for PXELINUX. However, 0x80 is out of spec for PXELINUX. If the BIOS doesn't do what you want for any of these defined values, then it is not at all clear to me that there is anything that we can do about it. I don't know what to suggest. ** Package changed: grub2 (Ubuntu Maverick) = syslinux (Ubuntu Maverick) -- grub hangs at early booting after handoff from PXE https://bugs.launchpad.net/bugs/625383 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Colin, Spoke to Anouar and he agrees that it doesn't appear we can do anything about this.

Ameet, Colin, Just to clarify things (though I agree there is sadly little than can be done anyway) I marked this bug as affecting grub because (if I recall correctly) using Shift would still sometimes yield the GRUB menu.

Ok, apparently -1 works on the Inspiron 1545 as well, but this solution is not usable as it makes other machines (e.g. Toshiba systems) fail to boot in the same way described above. -- grub hangs at early booting after handoff from PXE https://bugs.launchpad.net/bugs/625383 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
